• Writing Scientific Articles: Guide For Dummies

  Publishing your results is a vital step in the research lifecycle, as it allows you to get your work seen by the scientific community, and exchange your ideas globally. But writing a scientific paper is not only about creativity, but also about good structure and following some key rules. If you don’t follow these rules, your article may end up being either boring or incomplete, which means that it won’t be cited. Jeffrey Robens, Springer Nature Journal development manager, conducted an open workshop at ITMO University, where he shared some advice on how to write a good scientific article.

• Scientists Develop Nanodiamond-based Controllable Light Source

  Physicists from ITMO University and Australian National University have developed the first-ever controlled nanodiamond-based light source. Experiments have shown that diamond shells can double the emission speed of light sources and help control them without any additional nano- and microstructures. This result was achieved due to artificially created defects in the diamonds’ crystal lattice. Results of this research are important for the development of quantum computers and optical networks. The study is published in Nanoscale.

• Scientists “Hack” Regulatory Mechanism of Immune Cell Activity

  An international research team has described new molecular mechanisms regulating the activity of macrophages, which are crucial elements of the immune response, in a breakthrough project. Macrophage activation is regulated by the level of itaconate, which has various effects on the production of substances causing inflammation. Regulatory pathways of itaconate and its derivatives are associated with the pathogenesis of some autoimmune diseases. Experiments on mice and isolated human cells have shown that these substances can significantly alleviate the symptoms of psoriasis. The results of this study are published in Nature.

• Physicists Create Crystal Lattice from Polaritons

  An international research team has produced an analog of a solid-body crystal lattice from hybrid photon-electron quasiparticles - polaritons. In the resulting polariton lattice, certain particles’ energy does not depend on their speed. At the same time, the lattice’s geometry, particle concentration and polarization properties can still be modified. This opens up new perspectives for study of quantum effects and the use of optical computing. Results of the study were published in Physical Review Letters.

• ITMO Researchers Develop Wireless Signal Transfer Method for MRI

  Scientists from ITMO University are the first to prove the possibility of wireless signal transmission in magnetic resonance imaging. Moreover, the resulting images are of even better quality than those produced using the common method of signal transmission over radio-frequency cables. This technology has already passed the first clinical trials on volunteers at the Almazov National Medical Research Center in St. Petersburg. It also received an award by the American Physical Society. The results of the research were published in Magnetic Resonance in Medicine, one of the most reputable scientific journals in the field of medical MRI.

• ITMO-Developed Nanoparticle Technology Helps Stop Internal Bleeding

  Scientists from ITMO University have developed magnetically-driven nanoparticles containing thrombin. A drug based on these nanoparticles can be injected intravenously and delivered straight to the site of a vascular injury to stop internal bleeding. It can accelerate local clot formation and reduce overall blood loss by up to 15 times. The nanoparticles are not toxic to humans and can potentially be used for safe treatment. The results were published in Scientific Reports.

• Researchers From ITMO Create First-Ever Light-Emitting Nanoantennas

  Young scientists from ITMO University have developed a new type of nanoscale light sources based on halide perovskites. The nanosources are subwavelength nanoparticles which serve both as emitters and nanoantennas capable of amplifying light emission inherently without need for additional devices. Moreover, perovskites enable tuning of emission spectrum throughout a visible range by varying the composition of the material. This makes the new nanoparticles a promising platform for creating compact optoelectronic devices such as optical chips, light-emitting diodes, or sensors. The results were published in Nano Letters, one of the leading journals on nanophotonics.

• ITMO Scientists Develop New “White” Near-Field Optical Microscope

  Scientists from ITMO University have proven that a silicon-gold nanoparticle can act as an effective source of white light when agitated by a pulse laser in IR band. One such “nanobulb” was integrated into a standard probe microscope, which allowed the researchers to overcome the diffraction limit and examine subwavelength-size objects. What is more, it made it possible to study the optical response of nanoobjects on the entire visual band, and not just in particular wavelengths. Not only will the new technology make modern near-field microscopy cheaper and simpler, but it also can find use in medicine. The scientists are currently patenting their invention, while its description has recently been published in the prestigious Nano Letters journal.

• Researchers Use Glass Microparticles to Enhance Solar Cell Efficiency

  Scientists from ITMO University have developed a new solar cell coating based on amorphous silicon that combines the features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid the overheating of solar cells, thus increasing their overall efficiency by 20%. Moreover, the suggested method is highly suitable for industrial needs due to its relatively low cost and simplicity. The research was published in Optics Letters.
